​​I write about the fundamental nature of the self and mind, especially from the vantage point of issues in philosophy of mind, metaphysics, cognitive science, applied ethics, astrobiology and AI. The topics I’ve written about most recently include the mind-body problem, spacetime emergence, superintelligent AI, the nature of life, the mathematical nature of physics, whether the mind is a program, and the nature of the person. Discussions of my work have appeared in The New York Times, Wired, Science, Big Think, Nautilus, Smithsonian, Discover, PBS, and more (for some of this, see “media”, above). See "papers" in the menu for downloads (also available at Academia.edu).
